Description
| Product Name: | Anti-Mouse IL-21R (Clone 4A9) In Vivo Antibody - Low Endotoxin |
| Product Code: | IVMB0283 |
| Size: | 1 mg, 5 mg, 25 mg, 50 mg, 100 mg |
| Clone: | 4A9 |
| Protein: | IL-21R |
| Product Type: | Monoclonal Antibody |
| Synonyms: | Interleukin-21 Receptor Subunit |
| Isotype: | IgG2a |
| Reactivity: | Mouse |
| Applications: | B, FC, In Vivo, IP |
| Formulation: | This monoclonal antibody is aseptically packaged and formulated in 0.01 M phosphate buffered saline (150 mM NaCl) PBS pH 7.2 - 7.4 with no carrier protein, potassium, calcium or preservatives added. Due to inherent biochemical properties of antibodies, certain products may be prone to precipitation over time. Precipitation may be removed by aseptic centrifugation and/or filtration. |

| Purity: | ≥95% monomer by analytical SEC ⋅ >95% by SDS Page |
| Product Preparation: | Functional grade preclinical antibodies are manufactured in an animal free facility using in vitro cell culture techniques and are purified by a multi-step process including the use of protein A or G to assure extremely low levels of endotoxins, leachable protein A or aggregates. |
| Applications: | B, FC, In Vivo, IP |
| Reactivity: | Mouse |
| Host Species: | Rat |
| Specificity: | Clone 4A9 activity is directed against murine Interleukin-21 Receptor (CD360). |
| Antigen Distribution: | IL-21R is expressed on most B cells as well as some T cells and NK cells. |
| Immunogen: | Rat YB2/0 hybridoma transfectant cell line expressing truncated IL-21R |
| Concentration: | ≥ 5.0 mg/ml |
| Endotoxin Level: | < 1.0 EU/mg as determined by the LAL method |
